Geotria is the only genus in the lamprey family Geotriidae. It has 2 known species: Geotria australis (pouched lamprey) and Geotria macrostoma (Argentinian lamprey). Both species were considered conspecific until G. macrostoma was revived in a 2020 study.
The family Geotriidae is most closely related to the lamprey family Mordaciidae, which has a similar Gondwanan distribution, and both families diverged during the Early Cretaceous. Together, their common ancestor diverged from the Petromyzontidae during the Middle Jurassic.
